A young person’s data points about healthcare costs are useless. It’s the 50s and 60s that get you, and when you actually need healthcare.
My brother in law is a low income 1099 earner and gets a special insurance for his kid that’s about $30, called PeachCare and it maxes out at $70 for 2 kids. Depending on income it’s $10-$35 dollar max per child.
My point is that there are significant healthcare costs, well into the tens of thousands of dollars, in one's 50s and 60s, and the data supports it. I don't know what the situation is if you earn $50k from investments every year, as I'm not familiar with the subsidy rules, but it would seem strange to me if the US government offered subsidies to someone drawing investment income from $3M.
Edit: It seems that you can get subsidies even if you are deriving your income from investments, so I guess you are correct that someone earning $50k doesn't pay the full premium price.

Personally I paid about $30 per month working part time as a waiter in college making about $20k a year.
